How to use fish pond aerator in high temperature season

The rational use of aerator can not only prevent and reduce the floating head, but also improve the water quality, strengthen the material circulation in the pond, weaken or eliminate harmful toxicants and promote the reproduction of plankton. So, how to use the aerator correctly?

1. At noon on a sunny day during the high temperature in summer and autumn, especially in fish ponds with fertile water quality and rich phytoplankton, the impeller aerator should be turned on for 2-3 hours. Because in high temperature and sunny days, the photosynthesis of phytoplankton is particularly strong and will produce a lot of oxygen, while in fish ponds with fat water quality, the light can only reach a depth of 20-30 cm, resulting in the saturation of dissolved oxygen on the surface of the water, while the dissolved oxygen at the bottom of the water is relatively low. The impeller aerator has the function of lifting water upwards. when turned on, it can cause the vertical circulation of the fish pond water body, make the dissolved oxygen of the whole fish pond water body reach saturation, and play the role of desalination, purification and improvement of water quality.

2. In the "south-to-north" weather, the upper and lower layers of the pool water convection rapidly, and the oxygen content in the pool will decrease rapidly. At this time, it is necessary to turn on the aerator early and open more aerators. If the sun is strong and the temperature is high during the day, there is a sudden thunderstorm in the evening, and Rain Water, who has a lower temperature, enters the fish pond in large numbers, which will cause sharp convection in the upper and lower layers of water and cause the fish to float, so the aerator should be turned on in time to increase oxygen.

3. When the "oxygen debt" is large, it is necessary to turn on more aerators. When there is no rain for a long time and the water temperature of the pond is high, a large amount of feeding will result in excessive water quality, low transparency, more organic matter in the water, large oxygen difference between the upper and lower layers, and large debt of oxygen debt in the lower layer. If new water is not injected for a long time, the water quality will be too fat and deteriorate, resulting in anoxic floating head dead fish.

4. The impeller aerator should be opened 1-2 hours before and after feeding. The impeller aerator can stir the water body of the fish pond and make the water body form a circular flow. on the one hand, it can bring the taste of feed to all parts of the fish pond to induce food; on the other hand, it can make the fish form the habit of conditioned reflex.

5. It is generally not suitable to turn on the wheeled aerator in the evening. Because at this time, the photosynthesis of phytoplankton is about to stop and can not add oxygen to the water. after turning on, the dissolved oxygen in the upper and lower water is evenly distributed, the dissolved oxygen in the upper layer can not be replenished when it is reduced, and the dissolved oxygen in the lower layer is quickly consumed, as a result, the rate of dissolved oxygen consumption in the whole fish pond is accelerated.

6. In summer, fat ponds are often caused by lack of oxygen due to overdense fish mouth and oxygen consumption of other organisms, resulting in local or whole pond fish floating heads. Therefore, it is best to turn on the aerator at 1-2 o'clock in the middle of the night until the sun comes out at 7-8 o'clock the next morning, and the oxygen is made by photosynthesis by phytoplankton, and the fish does not float before stopping.
